Gerald Schwank
Group Leader
Gerald Schwank was a graduate student in Konrad Basler’s lab at the University of Zurich, where he obtained his Ph.D. in 2009. As a postdoctoral fellow he joined the team of Hans Clevers at the Hubrecht Institute, where he established genome editing approaches in adult stem cell systems. Soon after, he started his own lab at ETH Zurich. While initially his team was dedicated to the establishment of genetic tools to study human disease mechanisms in stem cells and organoids, more recently they have focused on the development of in vivo genome editing approaches to cure monogenic diseases. In 2020 the Schwank lab has moved to the University of Zurich, where they continue to pursue their goal of generating novel genome editors and translating these technologies from bench to bedside.

Tatjana Haenggi
Lab Manager
Tatjana received her PhD from the UZH in 2004. In order to see more of Europe, she moved to London to work as a post-doc at the University College London. Her project focused on a gene therapeutic approach for seizure suppression in a rat model of focal neocortical epilepsy using HSV vectors expressing galanin. In 2019, she joined the Schwank group as a lab manager. In her free time, she enjoys the company of her husband and her two teenage sons.
